• My preferred way to do it is to form a box that is missing 2 sides. One of the open sides faces the back of the fence at the cut out, the other is on the table top. Fix this to the back of the fence and then cut an opening to accept the dust extraction hose. This draws air up from where the router is and is pretty effective in terms of dust collection.

    If you are not using a fence and are going freehand or using a bearing guided bit then dust collection is not as important from a quality standpoint but you will need to have a dust mask on. If you really want dust extraction without a fence you need to form a box around the router, and well still need a dust mask as this is not nearly as effective.
